Abstract

Mirror apparatus for examining body cavities such as the mouth including a handle having inner and outer end portions, valve apparatus connected to the outer end portion of the handle and a syringe tip connected to the outer end portion of the valve apparatus. A detachable elongated body cavity member for insertion into a body cavity is provided that can be placed on or removed from the syringe tip as is a detachable mirror assembly that can be placed on or removed from the outer end portion of the body cavity member. The body cavity member has an elongated fiber optic member that can be connected to the end of a flexible fiber optic bundle so that light can be projected onto the mirror surface. The valve apparatus has manual push buttons that permit the delivery of air, water or a spray of air and water to the mirror surface for cleaning the surface. Both the body cavity member and the mirror assembly are made from materials that permit them to be subjected to thermal sterilization.
